Definitions
- the invention relates to a method and an apparatus for producing fuel gas from carbon-containing
- Products in particular from waste and residual materials that are suitably conditioned or prepared.
- DE-OS 33 12 863 a method for burning combustible material, in which combustible exhaust gases are fed to a combustion chamber, is known.
- the exhaust gases are guided separately from within the combustion chamber to its outlet or its outlets and fresh air is added to the separately guided exhaust gases. This is to enable the exhaust gases to be burned out as completely and trouble-free as possible.
- gas generators in a structural unit with a combustion chamber are known as so-called gasification boilers. These consist of one arranged above a movable grate
- the invention has for its object to increase the purity of the gas produced and thus to expand its usability, combined with a complete utilization of the carbon contained in the waste or residual material used, an optimal utilization of the fuel gas generated and with a minimization of pollutant emissions. inert due to the combustion exhaust gases emerging after the removal of heat.
- the object is achieved in that, in accordance with the method, the appropriately conditioned or prepared waste or residual substances are gasified as solids with air or an air or oxygen-containing gas mixture as gasifying agent in a gasification apparatus.
- the substance to be gasified and the gasification agent are guided in the mixed stream by the solid to be gasified passing through the gasification furnace from top to bottom and the gasification agent both from above and from below and to the side, or at least to the side and at one of the other locations mentioned Solid bed is supplied and the fuel gas is preferably withdrawn on the side opposite the lateral supply of the gasifying agent.
- the gasification process in the gasification apparatus is regulated according to the invention by recording the temperature profile over the height of the gasification apparatus.
- the position of the main gasification zone, corresponding to the maximum temperature zone, is determined by the movement of the sliding grate and thus regulated by the ash discharge.
- the optimal gasification temperature which differs depending on the type of waste or residual materials, is regulated by the size and composition of the gasification agent flow and the power of the gasification furnace by the width of the gasification agent supply by means of supply points arranged one above the other.
- the fuel gas generated can be supplied completely or partially without further processing to a combustion chamber which is arranged in a unit under the gasification apparatus, and the combustion gases which are produced can be used thermally.
- the fuel gas is advantageously fed to a machine for generating electrical energy.
- the residual heat is used thermally by means of a waste heat boiler.
- the combustion exhaust gas is subjected to flue gas cleaning, which preferably includes an activated coke filter, and then reaches the atmosphere via a chimney.
- the device for the production of fuel gas by gasification of carbon-containing products, in particular of appropriately conditioned or prepared waste and residual materials, with air or an air or oxygen-containing gas mixture as gasification agent in a gasification apparatus, preferably in a structural unit with a combustion chamber is characterized in that the gasification apparatus is equipped with an inclined grate, which is preferably designed as a stepped grate, which enables the gasification agent to be supplied and can be set into a pushing movement by means of a suitable mechanism.
- the gasification apparatus is surrounded by a two-layer insulating-cooling system, the layers of which are separated by a perforated intermediate wall, the outer insulating layer having one or more openings for the cooling Air inlet and the inner cooling layer have one or more openings for the cooling air discharge.
- the gasification apparatus according to the invention is equipped with an inclined grate 1, part of the gasification agent being supplied to the substance to be gasified through this grate 1 and mainly having the task of completely converting the carbon still present in the feed ash.
- Another portion of gasification agent is fed to the gasification furnace above the solid bed and has the main task of flushing smoldering products of the material to be gasified into the gasification zone and thus supplying the complete gasification.
- the majority of the gasification agent is fed to the gasification apparatus laterally via a feed 2.
- the dimension of the gasification zone and thus the gasification performance can be determined by varying the width of the gasification agent supply at the side.
- the mixed stream gasification according to the invention achieves on the one hand a complete conversion of the carbon contained in the substance to be gasified and on the other hand a complete conversion of the primary smoldering products so that the fuel gas is free of condensable organic and tar-like substances.
- the inclined grate 1 is designed as a stepped grate or in another way deviating from a flat shape and is movably mounted as a sliding grate.
- a suitable drive 4 is carried out, the ash is discharged through a discharge opening 5 and reaches the ash chamber 6. Due to the spatially separate removal of fuel gas and ash, the fuel gas is largely free of carbonaceous and mineral particles.
- Another feature of the invention is the insulating-cooling system around the gasifier.
- the cooling air first passes into an outer insulating layer 7 and from there through the perforated intermediate wall 8 into an inner cooling layer 9, where the actual cooling of the gasification furnace jacket 12 takes place.
- the preheated air leaves the insulating / cooling system at an outlet 10 and is used as a gasifying agent or combustion air.
- the regulation of the gasification process in the gasification apparatus takes place, as already described, by recording the temperature profile over the height of the gasification apparatus.
- the position of the main gasification zone, according to the maximum temperature zone, is regulated by the movement of the grate 1 and thus by the ash discharge.
- the optimum gasification temperature which varies depending on the type of waste or residual material, is regulated by the size and composition of the gasification agent flow and the power of the gasification apparatus over the width of the gasification zone, corresponding to the width of the gasification agent feed, by means of several feeds 2 arranged one above the other.
- the fuel gas generated can be supplied completely or partially without further processing to a combustion chamber 11, which is arranged in a unit under the gasification apparatus, and the resulting combustion gases can be used thermally.
- the fuel gas is fed to a machine for generating electrical energy.
- the residual heat is used thermally by means of a waste heat boiler.
- the combustion exhaust gas is subjected to flue gas cleaning, preferably using an active coke filter, and then reaches the atmosphere via a chimney.
